IMPROVED CAR-HIMPER.

The Schedule referred, to :Lu these Lettera Patent and making part of the same.

dab-

To all whom 'it may concern:

Be it known that I, CHRISTOPHER C. Dow, of the city-and county of Philadelphia, and State of Penn- Sylvania, have invented a new and useful Improved Portable Gar-Jumper;. and I do hereby declare that the following is a full and exact description thereof,

reference being had to the accompanying drawings, and

.to the letters of reference marked thereon.

The nature of my invention consists, in the first place, of two sheet-iron plates, which I usually make of boilerf iron, hinged together, so as to be folded, to be conveniently carried under the seat of a car, when notin use, to be placed on a track, over hose, in time of fire, to probeing one pair of plates to be placed over each rail of the track; The-plates are elevated at their central or hinged ends when in this position, and have but-joints to give them firmness in their arched or angular position, so as not tobear upon the hose when cars pass over them. 'The plates are provided with supplemental rails, which "are beyelled on their under sides, at their outer ends, to present a continuous surface with the tread of the rails of vthe track, and thus afford a free-running ofthe wheels of the cars. The outer ends of the hinged plates are bevelled off in like manner, to form a continuous surface with the track.

The invention, in the second place, consists of adjustable feet to Vthe hinged plates, in adaptation to the inequalities of the road; and,

In the third place, in supplemental hinged plates, which, b y their weight, adjust themselves to the track on each side of the track-rails.

The first-mentioned hinged plates are wide enough to have a sufficient margin, on each side of their rails,l to compensate for any irregularity of running ofthe wheels, of vehicles which are not of the saine distance apart as the wheels of the cars; and, to this end, the supplemental plates are so combined and arranged withthe others, whichare cut out in their corners to receive them, as to come, at their outer edges, just outside of and at their inner edges, inside of the flanges of the same.

In the accompanying drawings- Figure l is an isometlical view of 'a jumper on one rail of a track.

` Figure 2 is alike view of the jumper in its reversed position.

Figure 3 is an edgeview of the jumper folded together for convenience in carrying it.

Like letters in allthe figures indicate the same parts.

AA are plates, which I usually construct of boileriron. They are connected together, at their inner ends, by means of hinges a a, and have a butjoint,b, which,

in conjunction with the hinges, gives a rm support to the plates as the cars pass over them, so as not to bear upon hose which they cover.

Y There are four pieces of hose, B, represented as crossing the track, in fig. l, over which the jumper is placed.

In practice, I place a jumper, as represented, on each rail, over any convenient number of hose.

C C C C are adjustable feet, which are connected with the plates AA, in adaptation to dierent heights of tread-rails of the tracks, and to the inequalities of the latter.

' In order to adapt the jumper to vehicles whose wheels are not of the same distance apart as the wheels ofA the cars, and to irregularity in running, I construct the plates A A considerably wider than the tread-rails D of the track, and I cut away the outer ends of said plates, so as to receive the supplemental plates Ax A1 and Az A2, which are connected to the former by means of the hinges c, so that by their Weight, as they turn freely on their hinges, they adapt themselves to the road, the plates A falling just inside of the iiange of the rail D, and the plates A2 outside of the tread.

These plates have bevels d on their under sides, at

their outer ends, so as'to bring their upper surfaces continuons with the track at each side of the' rail. The remaining portion ofthe ends of the plates A A, and the outer ends of the continuous rails E E, which are confined to the plates by means of rivets, have like hevels d, so that the plates may form a continu,

the track,

ous surface with the flange of the rail of andthe rails E, a like surface with its tread.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination of the plates A A, having hinges a and a but-joint b, so as to form a solid arch over the hose, the said plates being provided with supplemental rails E, substantially in the manner and for the purpose above described.

2. The combination of the adjustable feet G with the plates A A, substantially in the manner and for the purpose speciiied.

3; The combination 4and arrangement of the supplemental plates Al and A? with the plates A, substantially in the manner above described, and for the purpose specified.

In testimony that the above is my invention, I have .hereunto set my hand, and' a'ixed my seal, this 28th day of September, A. D. 1868.
